The Chiefs came out of the gate leaning heavily on Jamaal Charles in Sunday's season opener against the Jacksonville Jaguars but Kansas City's featured back hasn't taken a snap since limping off the field in the third quarter.

The team announced Charles is questionable to return after sustaining a quad injury. He was seen riding a stationary bike along the Kansas City sideline before retreating to the locker room. Charles exited the game with 76 yards rushing on 14 carries. His 2-yard score in the second quarter gave the Chiefs a convincing 21-2 lead at halftime.
